yes it's hard and yes it's definitely a challenge but as someone who's getting married in less than a month I'm not going to let thees take away from the simcha of the biggest day in my life
I spoke to a friend of mine who married off his son on lag bomer. They had to change venues the day before the chassuna.
He told me that the chassuna was beautiful, close family and some friends of the chosson kallah about 70 people in all. He said everyone there gave it their all and it knocked. I compared it to an out of town chassuna. Less people but the people are there to stay not running in for a quick mazal tov but actually being misamech the chosson kallah.
Mazal tov and hatzlocho!
